IN CINE RA'IOB. l

To all whom 'it may concern:

Be it known that I, GAeRiEL ALLEN, a citizen of the United States, residing at'Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Incinerator, of which the following is a specification.

Th particularly to that class of furnaces known as incinerators adapted for the destruction of refuse material.

One ofthe objects of this invention is to provide an improvement in incinerators designed to consume refuse material of various characters, some of which aswagonloads of damp or wet garbage, may require one kind of treatment, and others of which materials, as loads. of dry substances, as paper orfother readily combustible substances., may -be consumed with greater ease, while other materials as tin Vcans and the like may require intense heat. for their destruction. The invention includes a furnace especially adapted for the treatment of :these different kinds of material; provision being made for readily depositing the more combustible materials where the heat4 therefrom will b 'e most effective to reduce the less combustible materials.

In carrying out this invention the top of the furnace is provided with an intermediate opening in, its top and with side openings on opposite opening, each ofl'saidopenings being arranged to deliver into the interior of the furnace materials dumped through said openings respectively, and there .is provided in the bottom of the furnace a grate for suspending any material which may reach the bottom of the furnace and the space`between the intermediate opening and such grate is open to allow material dumped through said opening to fall directly onto the grate; but underneath each of the side openings is a basket, the adjacent sides of said baskets being spaced apart from top to bottom to provide the open space below the intermediate opening through which the material dumped through said -inter1nediateopening-may fall directly -to the grate, while the vmaterial dumped through either of theside openings will be 'caught by the basket below such opening.

' vBy the arrangement above described the attendant is enabled to deliver to the furis invention relates to furnaces, and' sides of the intermediate Specification of Letters Patent. i Application filed June 5, 1906. Serial No. 320,295. l

Patented-Feb. 1e, isos.

nace in the simplest and most eiiicient manner andfwith the greatest economy of time and labor, the materials necessary to cause the most rapid incineration of the material required to be burned, the dry-and combustible material bei-ng dumped into the intermediate opening while the damp, Wet and more incoinbustible materials that require intense heat will be dumped into the side openings and thus into the baskets. In Athis respect I regard my present invention as a pioneer invention for the reason that the at.- tendant is enabled to deposit the dry ma.q terial with minimum labor and time, exactly where he desires to deposit it, in order to accomplish the incineration with the greatest expedition.

y dumping the .readily combustible material onto the middle of the grate the combustion vof the same will .occur most readily at the sides of the heap, of :material fthus dumped, for the reason that' the air may flow there upward through the grates more readily owing to the smaller quantity of material on the grate at the sides' of suoli heap, the lines of fiercest combustion are thus brought underneath the baskets-'coni taining the damperv and wetter inaterial. Provision is made in combination with the arrangement above set forth whereby the furnace may be supplied with large quantities of oxygen. This is accomplished by means of hollow and perforated grates which may be of any well known or approved form.

Another and a very important object of this invention is the provision of certain means for intensifying the heat and for centinuing the tire in the crematingchamber by. means of the garbage itself without the use of additional 'fuel. These means comprise a grate composed] of a series of hollowedA members havin perforations upon `oneside whereby air is forced therethrough.

With these and other objects in view, this invention consists in the features, details of construction, andv combination of parts, as will be described. in connection with the companying drawing, and then be more particularly pointed out in the claims.

The accompanying drawings illustrate the invention.

.Figure 1 is apfragmental sectional per` spective view of an incinerator constructed in accordance with this invention. Fig. 2 is avanza 'site corr 'the heat. I cl designates the dempers. Con- E nected with said cylinders G are a plurality tire-brick walls 2 forming the walls of the i eremating chamber, provided with a .plurality of openings 4 rec.- tangiilar in shape, or round if desired, and with an elongated opening i forming a con'- 'l`lie upper wall 3 lis y lveyer pit extending nearly across the entire l top of the furnace. These openings or eon- 1l I completed.

rcver pits communicate with the interior of the creinatoi'y and are arranged to have the 1 i5 material to be iiiciiieiated dumped there through. In the interior ot said ereinating chamber are a plurality of cylinders (S hav'- ing removable headers T for the purpose of allowing the saine to he cleansed of any iinpui-ities. These cylinders contain water, the water letelin both being equalized by the tube S, and the` equalization of the steam pressure being etl'ecte'd by tle tube 5) coni into au.air reservoir QT which carries a numnecting the two cylinders. it plurality of safety valves 10 are mounted in operative relation to said cylinders. These cylinders are carried by and mounted upon supports i or standards 1l, which in tui-ii are supported by au I-beaml l2 extending horizontally 30 across the width of the furnace. Connected with the cylinders are a plurality of tubes 123 depending into the cremating` chamber and to be operated,-that is, tliiiiiped,-witliout extending away to the walls Q thereof where f they connect with a water-supply cylinder 14 having an inlet 15. The water in said cylinder 1l may be heated by an oil-burner or in any other manner, and as the water is heated therein it is forced through the tubes or pipes 13 upward into the cylinders G. 40 Upon these tubes which form substantially a basket or grate the moisture-containiug product is allowed to be deposited and there held in suspension until practically all the moisture has been evaporated therefrom, the 45 heat in the tubes contributing to this process.

As will be seen from tlie drawing, the cylindeis aswell as the tubes are spaced at a predetermined distance, and the top of the oven provided ."with the aforementioned conveyer pit 5 foiii'tli'e-piirpose of allowing dry materials o "y pilbdiiicts to be dumped. therethroigliiyyithout lodging upon the baskets or tubes, but falling directly on the grate where they are consumed and reduced to ashes. 16

represents adamper-controlled flue or stack communicating with the atmosphere and the interior f r-'the cremating chamber,v which stack e endsto" the exterior of the furnace and away from the conveyer-pits, so that the dumping of garbage and material to be inoinerated is not interfered with.- Two of these stacks ai'e provided as shown, one'at 1G and one at 17, both being damper-controlled and operating to increase the circulation of the draft' in the furnace and intensifying of Vpipes 18 and lil, the pipe 1S being counected with a water-level or indicator, and the pipe 1.9 being connected with La steam register 2l for indicating the pressure of steam within the upper pai't of the respective cylinders 6. plurality of lateral open- 52 communicate with the interiorof the. baskets or gratos for the purpose of dislodging the burned and dried products on to tlze `ofi-ate below where the incineration is zer of ero`s valves Q8 designed to control 90 the air within .said reservoir.l AThe ends 0f thev grate bars are hollow, as well as the grate bars theniseli'es aand are .Cwiyeled to said reserroir for the purpose of allowing the same I interfering with the liow of air-'from the resl vervoir 2i. The cross alves 2S independently control the admission of aii to each individ ual section ot the grate bars, thus admitting of tlze niorespeedy incineration/ofv products i on various parts of the grate, which fact is a decided advantage ina garbage ineinerator,

for the reason that when the materials are dumped into the garbage-supporting grates or baskets a considerable amount of moisturecontaining material or garbag 'may fall through and lodge on the fire-g te below, lwhich in ordinary cases would not be able to destroy the same, but on the other hand,

the garbage would in all likelihood extinv A `guish the tii'es. The air is supplied tothe grates by means of an ainpiimp whereby any degree, of pressure may be attained as may he desired hy the operator.

2t) indicates the supply for the air reser- 115 voir Q?, the pipes 30 for conducting the air to the reservoir being formed in ya coil and located and inclosed within a steam jacket 31, .whereby the air in its passage through said pipes is heated and reaches the grate bars in a heated condition, thus'doublyfi'ntensifying the heat `within the cremati'ng chamber to consume the material upon "the grate-bars. i y -1 32 shows the inlet ,supply for steam, the. 125l ordinary steam trap for vcondensedwiztt'ers and the usual fety valves not being 'shown y in the drawin. The steam jacken/as will be seen,` is inclined with respect to the lateral V, walls of the furnace and servesl aside from 13'0 massi -may drip from the baskets or grates through there-grate upon said steam jacket. lt is obvious, however, that on account of the intensied heat produced Within the ereinatory by reason of the hollowed and perforated grates, the process of evaporation of any moisture which may escape from the bulk of the material, is almost instantaneousdandpractical demonstration has shown that if moisture exists to such an extent that it falls in drops it is evaporatedbefore itreaches Y the grate. However, as an extreme precaution, thelsteam jacket is provided to assist in evaporation of moisture Within the furnace, but' serving principally asl an ashchute for the `gratos above.y

A plurality of; lateral openings 33 are provided in the incinerator between the tiregr'ate andthe garbage-supporting'grates or baskets'l for the purpose lof removingtlie burned products from the tire-grates'if such 'should remain glu' operative relation to the steam jackets is a scraper operable from 'the outside of the furnace and designed to convey the ashes to a car 34 placed in liue with the opposing steamA jackets 'which are spaced apart and suitably supported. This scraper comprises an endless chain 35 mounted on y sprockets 36, and a plurality of transverselyexteiiding blades 37 positioned uprightly' with respect to vsaid chains and operating' as they are revolved to force the ashes into the car 34 whereupon it is shoved or moved away :from the furnace and another hroiufht-'iuto place. This scraper is operated by the ordii'iary crank, as shovvn at.`38. All of the gratas may be operated by a single lever andbar in any usual manner, which of course d'ispeiises'with the necessity of stokthe tires through the openings 33.

The construction ofthe incinera-tor as herein represented and' described, is provided with Walls having a plurality of keys '39 made allotl tire-brick and having an exterior metalliclining fixed thereto, as for instance, by bolts 40. This dispenses with the use of metallic steam-containing walls and insures the retention of the heat within the erematingg' chamber. y

The equalizing' means for the steam, shoivn at i), serves to support the arch thereabove, although the arch is, culiar formation of the brick as shown,l selfsupporting. The cylinders have a lug or lip 41 provided on their sides for the purpose of supporting the arch 42.

ln vpractical use theloads of refuse niaterial may be dumped in the separate lines of olpenings a and 5 as may be judged advisa le by theIl attendant. vThe dry and readily combustible material may be dumped into tle center opening' 3 in great or small quantities andvfalling` upon'tlie tire-grate .left of the central passage way leading downward from the middle opening or eonveyer pit The baskets curve ul'iu'ardly from the side ivalls to the upper ends at the opposite sides of the pag. age way below the ,opening 5, so that the material therein is subjected to the heat of combustion ot' the more combustiblematter on the A Having, thus described and aser nature ot my invention, what l claim and desire to secure by letters-Patent of the United States is l. An ineinerator con'iprisinga casing] ing a chamber, a ire-grate and a pliu Y of baskets in the chamber, said baskets being` formed of pipes andiarraiiged to hold moisture-containing products in suspension above the grate, and being spaced apart and separate from each other with :in open space between them at their tops and 'divergingr downwardly to provide a p ssage-u'ay from said open space to the iirograte; meansI for supplying' water to the pipes of said baskets;
